Early pick-up (≈06:30) from your hotel and drive 5–6 hours via the Ngorongoro highlands to enter Serengeti at Naabi Hill Gate. Enjoy a picnic lunch, then an afternoon game drive across the Seronera plains—prime big-cat country with frequent sightings of lion, cheetah and (with luck) leopard along the river lines and hippo pools. Continue game viewing en route to your lodge/tented camp, arriving by sunset for dinner and overnight..

Pre-dawn breakfast and depart ≈06:00 for the crater gate; descend 600 m to the floor for a focused 5–6-hour game drive (crater permits allow one entry with a limited time window). Explore Lerai Forest for elephants and leopard, Lake Magadi for flamingos and hippos, and open grasslands for lion, buffalo and (with luck) black rhino. Picnic lunch at the hippo pool, then ascend the crater rim and drive back to Arusha (arrive ≈17:00–18:30) or continue to Kilimanjaro Airport on request. Pack a warm layer for the cool morning at altitude; afternoons can be dusty and sunny.
